Abstract: A detachable accessory for stringed instruments of the guitar family that utilizes a platform (26) to support individual string contacts (37-42) from a position over an instrument's strings (21-24) near the bridge (20). The contacts (37-42) provide adjustable, curved surfaces for the strings (21-24) to rebound against as they vibrate, causing them to emulate the timbres of other instruments, such as a fretless bass, or a sitar. The device can be attached by double-stick tape or foam, and no alterations are necessary on the instrument.

Abstract: An external support system that connects an electric guitar module (90), such as a travel guitar, to a standard electric guitar (80) or bass by detachably anchoring a linear holding device (20) to the standard instrument's body. The holding device (20) causes no alterations of the standard instrument, attaching to a posterior strap-fastening anchor (84) and an anterior horn-shaped curvature (86) to provide a slideable locking means (54) which fastens the external module (90).
